Researchers have mapped immune responses from one of Australia’s first COVID-19 patients, showing the body’s ability to fight the virus and the timing of recovery from the infection. Researchers were able to test blood samples at four different time points in an otherwise healthy woman in her 40s, who presented with COVID-19 and had mild-to-moderate symptoms requiring hospital admission. A report on the work in in Nature Medicine outlines how the patient’s immune system responded to the virus. One of the authors on the paper, Oanh Nguyen, a research fellow at the Peter Doherty Institute for Infection and Immunity (Doherty Institute), a joint venture between the University of Melbourne and the Royal Melbourne hospital, says this marks the first report of broad immune responses to COVID-19. “We hope to now expand our work nationally and internationally to understand why some people die from Covid-19…” “We looked at the whole breadth of the …
